Add field in DataObject in PowerBuilder

Question

I am new to PowerBuilder and I need to add a new column to a DataObject. The DataObject has several fields which retrieves data using select statement. So if I add a column in the select statement I get another field with a name compute_0041 along with the added column field. When i try to remove the compute_0041 field I cannot see any value in the field representing a new column. How do I remove the compute_0041 that gets automatically added?

Thanks

In Datawindow if you accidentally put a 0 or '' in one of the rows in the tab called Computed Columns then these columns may come in. Of course, you can also have a computed column yourself by specifying it there but since it seems you think you didnt do anything and it came up on its own it appears to be an accidental issue.

You can of course check for it by going to the SQL mode and checking for it there. Also, the last tab in the design view it shows the complete generated SQL where you can easily see a select column that is not chosen by you.

Hope the above will aid you to identify the issue. Please let me know if you still have the issue.
